The status quo and future development direction of high efficiency and energy-saving motors in China
In 2016, China had gradually developed into a motor kingdom and already has efficient and ultra-efficient energy-saving motor production technology, but overall, the industry competitiveness is still weak. A large amount of motor and low energy efficiency is the most basic status quo in China. Compared with developed countries, there is still a big gap.
A large amount of application and wide application area is the most basic attributes of the motor industry. According to the Ministry of Statistics, the electricity consumed by motor accounts for 64% of the total electricity consumption of the whole society. The motor's energy consumption in the industrial field accounts for 70% of the total electricity consumption in the industrial field. More, compared with foreign countries, about 15% to 20%. Gao Dongsheng, deputy director of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, said.
According to the GB18613-2012 standard, China's current production and in-use motors are mostly Class 3 energy-efficient motors lower than the standard. However, the average efficiency is 87%, and the efficient motor efficiency implemented in developed countries has reached more than 91%. In addition, statistics from the Ministry of Industry and Information Technology show that the proportion of high-efficiency motors in domestic motors is only about 5%.
In recent years, although China has basically kept pace with the international level in the research and development of high-efficiency motors, the technological progress is very optimistic. But unfortunately, the IE3 motors produced in our country are used too little domestically, and most are used for export. Therefore, it is not difficult to see that China still has huge challenges in high-efficiency motors.
In the future, on the one hand, we should carry out in-depth research on energy-saving technologies for motors and their systems, such as research and development of energy-efficient motors; high-efficiency fans, pumps, compressor systems; high-efficiency transmission systems; reasonable matching of motor systems; and system integration solutions for energy-saving of motor systems. On the other hand, it is necessary to formulate guidelines and standards for energy-saving of motor systems, such as system energy-saving renovation, energy-saving testing, and evaluation standards for motor systems in special fields. In addition, we must establish a motor system energy certification agency, such as market access certification, energy-saving product certification, energy-saving certification of various high-efficiency motor systems. Thus, promote the development and speeding of China's overall industrial level.
